SAW SETTER. i

Application iled May 1l, 1921. Serial No. 468,51?.

To all whom t may concern: p

Be it known that l, ALVIN CAsnnnnn, a citizen ot' the United States, residing at Heppner, in the count)7 of Morrow and State of Oregon7 have invented certain'new and useful Improvements in Saw Setters,` of which the following is a specilioation., reference being had to the accompanying' drawings.

lt is the purpose of the present invention to provide a 'device of this character principally adapted for setting `teeth of cross cut saws, though it may be used for setting teeth for'hand and other saws, by employing different saw set blocks.

Another purpose involves a s w setting device including a head block provided with a transverselyY disposed dovetail groove for the reception ol? the sa-.w set block, in conibinationy with inea-ns for holding the block in position., f l

l'ltill another purpose is the provision ot a saw setblock having 'a "transverse depressionprovided with a beve-led wall7 contorxning to which the teeth of the saw may be set,V said depression having` a vertical wall, in which a notch is 'formed provided with an inclined bottoni, to which the beveled end ol.z the `tooth setting pin or screw conforms, as the tooth is set.

Still another purpose is the provision oi a spring tensioned lever carrying the tooth settingI pin or screw, to be moved toward the head block or base, :torsetting `each tooth olI the saw, as the saw is moved step by step transversely of the head block or base, in combination with an adjustable abutting screw to Contact with the saw on the base to limit the lever in its movement,

lVhile the design and construction at present illustrated and set forth is deemed pretorable, it is obvious that as a result of a reduction oli' the invention to a inore practical 'lorru for commercial purposes, the invention may be susceptible oli changes, and the right to these changes elainierhprovided they are comprehended Vwithin the scope or what is claimed The invention comprises further features and combination of parts. as will be hereinafter set forth, shown in the drawings and claimed. i

.ln the drawings:

Figure 1 is a view in perspective ot the improved saw set constiaictedin accordance with the invention. n l k l Figure. 2. is a longitudinal sectional view on line EZZ of AFigure 1, showing the tooth setting lever and the tooth setting pin or screw in the act ot setting a tooth of the saw. p

Figure 3 is a detail sectional view somewhat similar to Figure 2, showing another :torni of saw set block or anvilin place.

Referring to the drawings, `1 designates the head block or base, which `is provided with an integral handle 2. The upper face of the. head block or base 1 has a. transversely disposed (il pression 3 provided with under cut `beveled wallsll. One of these walls extend. at a slight diverging angle relatively to the other wall and across the head block or base, 'so as to permit the set block or anvil, 5 to be insertedA in the filepression or groove rorn one edge only ol the base or head blockythereby holding` the anvil or head block removably dovetailed in position. kThe set block` or anvil has a groove .6 comprising a vertical wall .7 :nul an inclined or beveled wall 8, which converges toward and merges into the vertical wall 7, consequently ythe depression is ol? vriangular shape'in cross section. A suit able set screw 9 engages through the set block-or anvil, and into the base or handle as shown, i-n order to hold the parts in position. p

.rlho 'vertical wall 7 of the transverse groove `(Sis providedwith a notch 10, the bottoni wall 11 of .which isinclined or beveled as'indicated.

Mounted `in any suitable manner as at 13 on the head block is an Yupright l-l provided with forks 15, there being a 4fulcruin pin 16 passingl through the forks and through one end 15T of the sawtooth setting lever 18.

This saw tooth setting lever has a socket' 19 near its pivoted end, for the reception ol! the upper rnd ot the coiled expansion spring 20, said spring beinglitted `over a pin 2l. to retain the spring in position, when the lever 1S is tiltednpwardly, and when the tension on the spring is reduced'. Si saw setting screw or pin Q2 is threaded at a sleeve portion 23 of the lever 18.l The lower end olf the tooth settingserew is tapered as shown at 24, and this screw is so disposed coincident to the notch 10, that the extremity of the screw will bear against the extremity of the tooth of the saw to be set, so that when the saw is disposed as shown in Figure 2, and the lever'depressed, the tapered end 24 of the tooth setting screw 22 will substantially engage andV conform to the inclined bottom 10 when the lever v18 is depressed toward the head block orbase. When the lever is depressed the tooth setting screw orv pin will bear against the tooth of the saw, and bend the tooth of the saw in conformity to the inc-lined or beveled bottom 8 of the depression or groove 6, thereby pitching the tooth of the saw according to the adjustment of the tooth setting screw or pin. ln other words should the tooth setting screw 'or pin be adjusted relatively tothe lever 18, so that'when the lever is depressed, the extremity' of the screw will move the tooth ofthe saw in contact with the inclined bottom 8.` However should the y tooth setting screw or pin be adjusted only al short distance toward the anvil or tooth' settingblock, the tooth of thesaw will be deflected or set to apposition slightly out of Contact with the bottom wall 8.of the groove `ordepression 6. lt is obvious that f other settingfbloclrs or anvils with shallower tapered impressions or groovestherein may be'employed, for setting the teeth of different .types of saws. The present device is particularly adapted for setting the teeth of a cross out saw,`though it is obvious that hand and other saws may be set, by employing other set blocks or anvils, with different forms ofy grooves or impressions 6 therein.

The inclined or beveled wall -of the notch 10 not only permits the screw 22 to be moved its full distance for setting the tooth of the saw, but also serves the purpose of the transverse corner edge of the extremity of each tooth `to conform thereto when set or deflected, without marring the extremity of the tooth.

' In yorder to limit the lever 18 in its movement vwhen setting the tooth of a saw,'an abutment screw 25 is threaded through `a sleeve portion 26 of the. lever 18, so that its extremity27 may abut the saw on the head block, This abut-ment screw limits the tooth setting screw in its movement when setting the tooth, so that the extremity of the toothr of the saw will' not be injured. In fact the tooth setting screw is limited, so that when `the lever 18.is` moved toward the base for deflecting or setting the tooth, the screw 22 will move the tooth of the saw just suiciently to bear slightly upon the inclined bottom or surface 8 of the groove or impression 6. e

One end of the vsetblock or base is prof vided with a ring 28 by which the saw set may be suspended from a nail or any other suitable device carried by astationary support.

A hook 29 is pivotally and loosely carried by the free extremity of the lever 18, so that the hooked end 29L may engage an eye 8O on 'the handle 2 of the base or head block, to hold the parts in position when the saw set is not in use.`

The invent-ion having been set forth, what is claimed as being useful is:

1. ln a saw set, the combination with a head block, of a saw set block detachably dovetailed in the head block, and provided with a saw tooth receiving groove, the bottom of the groove being beveled or inclined, and a tooth setting lever having a tooth setting screw movabletoward the groove or impression,` for depressing the saw tooth in engagement withA the groove, the vertical wall of the groove having a notch having its bottom inclined to guide the tooth setting screw toward the saw tooth and permitting the end ofthe-screw to overlie the saw tooth, whereby the extremity4 of the tooth may conform tothe inclined bottom of the notch when set.

2.111 a saw setter, a base, an anvil detachably carried by the base and provided with a triangular groove, one wall of said groove extending at an angle to the horizontal plane, the other wall having a notch provided with an inclined bottom extending vat rightv angles to the inclined bottom of the groove, whereby the end of a saw setting device may overlie the end of the saw tooth, when setting said tooth, thereby causing the extremity of the tooth to coliform to the inclined bottom of said notch, and a movable member provided with a tooth setting device to engage and set the tooth of the saw.

3. In a saw setter, a base, an anvil detachably carriedby the base and provided with a triangular groove, one wall'of said groove extending at an angle to the horizontal plane, the other wall having a notch provided with an inclined bottom extending at 110 right angles to the inclined bottom of the groove,'whereby the end of a saw setting device may overlie the end of the saw tooth, when setting said tooth, thereby causing the extremity of the tooth to conform tothe 115 inclined bottom of said notch, and a movable member provided with a tooth setting device to `engage and set the tooth of the saw, and means for limiting the movable member so that the tooth setting device will' 120 set the tooth to `conform to the inclined bottom of the groove of the anvil.

4. In a saw set, a'base, a tooth setting anvil removably carried thereon and provided with a groove angular in cross sec- 125 tion, one wall of the groove being inclined from a horizontal plane, the other wall being' vertical but at an acute angle to the inclined wall, the vertical wall having a notch having an inclined bottom extending 130 at an angle tothe inclined Wallyof *theY groove, a spring tensoned lever vfulcrumecl upon the base and overlying thegrooveof the anvil, a tooth settingsorew carried hy" conforms when the tooth is set by depressing the same into the groove, and means for limiting the lever in its movement When seti l0 i n l tino` the tooth.
